Dopamine receptor D2 gene polymorphism, urine fluoride, and intelligence impairment of children in China: A school-based cross-sectional study.
EXCERPTS … In China, endemic fluorosis is classified into drinking-water type, drinking-tea type, and coal-burning type. Humans are exposed to high fluoride mainly through drinking groundwater with high fluoride content (Barbier et al., 2010). When fluorine is absorbed, it enters the blood and distributes throughout the body, mainly in bones and teeth (Barbier et al., […]
